6 FAQs about [Photovoltaic battery capacity unit conversion]

How can battery capacity be reduced in PV-electrolysis hybrid systems?

The installed electrolysis capacity can be reduced by configuring a certain amount of battery storage to be discharged for electrolysis during peak load periods. This reduces the overall capital expenditure of the entire system. Therefore, the battery capacity configuration in PV-electrolysis hybrid systems is of particular importance.

Do battery capacity and output smoothing affect PV output?

If the PV system is grid-connected, batteries can reduce the fluctuation of PV output or provide economic benefits such as demand charge reduction, capacity firming, and power arbitrage. The work in analyzes the relation between available battery capacity and output smoothing, and estimates the required battery capacity using simulations.

How many kW can a PV panel produce by 2050?

(2) Considering the effect of the learning curve, by 2050, the capital expenditure of the PV panel and proton exchange membrane electrolysis can be dropped to 2981 and 1992 CNY/kW, respectively. (3) The optimal case considering uncertainty currently is a 1 MW PV panel equipped with 242 kW electrolysis and 2276 kW battery.

What is the maximum output of a PV panel?

The optimization results of the model considering the uncertainty of PV output show that the maximum actual output of the PV panel is 659 MW, which is lower than the 694 MW in the model without considering uncertainty. The PV output will decrease in the worst-case scenario. The cumulative power generation during a typical day also confirms this.

Can a fixed electrolysis efficiency estimate the capacity configuration of PV-battery-electrolysis equipment?

Most existing studies use fixed electrolysis efficiency to roughly estimate the capacity configuration of various equipment in the PV-battery-electrolysis system. This assumption leads to errors in capacity configuration results and cannot accurately characterize the real-time operation status of each piece of equipment.

Is a battery a good choice for PV systems?

The benefit of increased self-consumed electricity is lower than the battery cost. Therefore, it is not attractive for users to install battery for PV systems. A sensitivity study about the battery price is carried out. When the battery price drops 50%, SSR and NPV of different combinations are shown in Fig. 15 (Blue Triangle Marker).
